JOHN KILDUFF, OF JOHNSTOWN, PENNSYLVANIA.

COMBINATION FORGE AND PRESS.

Application filed December 18, 1912.

To all whom it may concern Be it known that I, JOHN KILDUFF, a citizenof the United States of America, residing at Johnstown, in the county ofCambria and State of Pennsylvania, have invented certain new and usefulImprovements in Combination Forges and Presses, of which the followingis a specification, reference being had therein to the accompanyingdrawmg.

This invention relates to a combination forge and press, and the primaryobject of my invention is to provide rolls that can be advantageouslyused for forging and pressing billets, whereby the billets can beeventually shaped into articles of commerce.

Another object of this invention is to provide an apparatus that can beeconomically and expeditiously used for forging and pressing metal toincrease the tenacious nature of the same, without unduly rupturing,upsetting or impairing the lasting qualifications of the metal.

A further object of this invention is to provide an apparatus of theabove type that has adjustable rolls that can be set to operate uponbillets of various sizes.

With the above and other objects in view the invention resides in thenovel construction, combination and arrangement of parts to behereinafter specifically described and then claimed.

Reference will now be had to the drawings, wherein Figure 1 is a frontelevation of an apparatus in accordance with this invention, Fig. 2- isan end view of the same, Fig. 3 is an enlarged perspective view of aroll bearing, and Fig. 4: is an enlarged perspective view of a detachedadjusting wedge.

Further describing my invention in detail with reference to theaccompanying draw ings, wherein like numerals denote corresponding partsthroughout: 1 denotes a bed plate provided with housings 2 and 8 andarranged within the openings 4 of said housings is a stationary bearing5, and an adjustable bearing 6 for the necks or spindles 7 of a roll 8.The roll 8 has the periphery thereof provided with a longitudinal recess9 of compound curvature thereby providing a shoulder 10 and it isagainst the shoulder 10 that the end of a billet is placed that passesunder the roll.

The bottom of each of the openings 4 of the housings provides a guidefor adjust- Specification of Letters Patent.

able bearings 11 that have depending flanges 12 engaging the sides ofthe housings. The bearings 11 are provided with seats 18 and let for thenecks or spindles 15 and 16 of rolls 1? and 18 respectively. The seats13 and 14; are formed whereby the strength of said hearings will not beimpaired by the formation of the seats, and in consequence of thearrangements of the seats it is neces sary that the roll 17 be of lesslength than the roll 18.

The rolls 17 and 18 of one set of bearings cooperate with the rolls ofthe other set in supporting a billet that is fed beneath the roll 8 tobe forged and pressed thereby.

The bearings 11 have inclined walls 19 provided with dovetailed tongues20 and these tongues engage in the dovetailed grooves 21 of Wedges 22arranged within the openings 4; of the housings. The wedges 22 areconnected by keys 23 to the lower ends of rods 24 that extend upwardlythrough the bearings 5 and 6 and the top of each housing, said rodsextending through a cross head 26 arranged above each housing. Extendingthrough the cross heads 26 are adjusting screws 25, these latter beingconnected to the bearings 6 whereby the bearings can be elevated orlowered in view of the fact that the screws 25 are verticallyadjustable. The upper ends of the rods 24 have nuts 27 and encirclingsaid rods between said nuts and the cross head 26 are coiled springs 28.The bed plate 1 is provided with a support 29 for a hydraulic cylinder30 and said hydraulic cylinder is employed for longitudinally moving ahead 31. The head 31 is adapted to engage one end of a billet thatpasses between the rolls of the apparatus and upset, compress or forgethe said end when desired.

In operation, the end of a billet is placed in the recess 9 against theshoulder 10 of the roll 8, and as movement is imparted to said roll orthe rolls 17 and 18 from a suitable source of energy, the roll 8 bringspressure to bear upon the billet and it is reduced in its crosssectional area, the rolling action forging and pressing the billetsimilar to the same action accomplished by a forging hammer.

It is apparent that by repeated passes and by turning a billet that itcan be quickly recluced to a desired size.

One embodiment of my invention has been illustrated in the accompanyingdrawings,

and modifications as fall Within the scope of the appended claims.

What I claim is 1. An apparatus of the type described comprisinghousings, roll bearings adjustably arranged in said housings, rolls supported thereby, adjustable Wedges arranged in the openings of saidhousings for shifting said bearings, and a roll adjustab ly andrevolubly support-ed by said housings and having a longitudinal compoundcurved recess formed in the periphery thereof presenting a longitudinalshoulder.

2. An apparatus of the type described comprisinghousings, roll bearingsadjustably arranged in said housings, rolls supported thereby,adjustable Wedges arranged in the openings of said housings for shiftingsaid bearings, a roll adjustably and revolubly supported by saidhousings and having a longitudinal compound curved recess formed in theperiphery thereof presenting a longitudinal shoulder, and'means adjacentto said housings for operating upon the side of a piece of materialpassed between said rolls.

3. In a combined forge and press, housings, adjustable bearingsarrangedin the openings of said housings, sets of rolls revolublysupported by said bearings, Wedges arranged in the openings of saidhousings and movably connected to said bearings, means supported by saidhousings for adjusting said Wedges, and a revoluble and ad justable rollsupported by said housings above the first mentioned rolls, said rollhaving a longitudinal recess formed therein presenting a shoulder.

In testimony whereof I afiix my signature in the presence of twoWitnesses.
